Getting error “Uncaught TypeEroror: cannot read property ‘moveToObject’ of undefined”  
also tried ‘moveto’.

I want to move a character object to the mouse click’s x position.

I think it’s a scope problem but not sure how to fix.

```
> class Game extends Phaser.Scene {
> constructor(){
> super("Game");
> }
> preload(){ //assume loading of everything is fine}
> 
> create(){
> let player = this.add.sprite(500, 400, 'char', 3);
> this.input.on('pointerdown', function(pointer){
> this.physics.moveToObject(player, pointer.x, 200);           
> });
> 
> }

```

Thanks in advance for help!

That means `this.physics` is undefined.

You can always pass context to `on()`:

```javascript
this.input.on('pointerdown', function(pointer) {
  this.physics.moveToObject(player, pointer.x, 200);
}, this);

```

Thanks @samme. If I do add this.physics.add.existing(player),  
and then add this to the end of the function as shown, the player character disappears altogether when I click!?

I think you need

```
let player = this.physics.add.sprite(500, 400, 'char', 3);

```

But check console.

Oh you need [moveTo()](https://photonstorm.github.io/phaser3-docs/Phaser.Physics.Arcade.ArcadePhysics.html#moveTo). Arguments don’t match.

THe problem with this is, it’s just floating my object randomly around the screen, not towards the pointer.x position.
